Drugs for Trichomoniasis

DRUGS FOR TRICHOMONIASIS

Trichomonas vaginalis is another flagellate protozoon which causes vulvovaginitis. A large number and variety of drugs are effective by vaginal application, but may not entirely clear the infection; recurrences are frequent; repeat courses are required.

1. Drugs Used Orally

Metronidazole 400 mg TDS for 7 days or 2 g single dose, or Tinidazole 600 mg daily for 7 days or 2 g single dose or Secnidazole 2 g single dose, are the drugs of choice. They produce >90% cure. However, vaginitis due to nitroimidazole resistant T. vaginalis is being reported from some parts of the world. Additional intravaginal treatment is required only in refractory cases. A hard core of recurrent cases may remain. A repeat course can be given after 6 weeks, and additional treatment for nonspecific vaginosis often helps. In some cases recurrences are due to reinfection from the male partner who harbours the parasite in the seminal vesicles but remains asymptomatic. In such cases, both partners should be treated concurrently to prevent cross infection of each other.

Nimorazole: It is another orally effective nitroimidazole; 2 g single dose taken with meals has produced satisfactory response in trichomonas vaginitis.
